BATON ROUGE, LA — The Louisiana Coastal Protection and Restoration Authority (CPRA) has selected the Archer Western-Alberici Joint Venture to provide Construction Management At-Risk (CMAR) services for the Mid-Barataria Sediment Diversion Project. The CMAR model integrates the construction contractor during the early design phase of the project to obtain input on cost, scheduling and constructability, which is anticipated to lead to lower costs and faster construction.
